Abstract

본 발명의 공기청정기는 사람 또는 불꽃을 일으키는 소리를 요염원으로 감지하여 공기오염을 신속학 판단하기 위한 음향센싱부를 포함하여 구성되며, 이를 통해 일정 시간 다단계의 음압신호레벨을 검지하여 단계별로 상기 송풍모터의 운전상태를 조절하고, 상기 음압신호레벨에 따른 송풍모터의 운전 후 일정시간이 경과하면 가스센서의 출력을 검사하여 상기 가스센서의 출력값과 음압신호레벨에 따라 다시 상기 송풍모터의 운전상태를 재조절함으로써 사용자가 오랜시간동안 오염된 공기에 노출되는 것을 방지할 수 있으며, 상기한 바와 같이 가스센서를 사용하여 공기오염을 재확인 이를 통해 구동상태를 수정, 보완함으로써 공기청정효율을 향상시킬 수 있는 효과가 있다.Air purifier of the present invention comprises a sound sensing unit for quickly determining the air pollution by detecting the sound causing a person or flame as a pollutant, through which the sound pressure signal level of the multi-step for a certain time through the blower step by step Adjust the driving state of the motor, and after a certain time has passed after the operation of the blower motor according to the sound pressure signal level, the output of the gas sensor is inspected, and the operating state of the blower motor is again determined according to the output value of the gas sensor and the sound pressure signal level By re-adjusting, the user can be prevented from being exposed to contaminated air for a long time. As described above, the air cleaning efficiency can be improved by correcting and supplementing the driving state through reconfirming air pollution using the gas sensor. It works.
